Sanding a slope/bevel in wood?

Hi all. So I'm building some new window cases for my garage windows and the bottom piece of the case needs to be sloped/beveled for water runoff. Does anyone have any suggestions as to how I exactly I could do this? Thanks.

In order to slope in a uniform manner, you need to run the piece along a fence. This is easily done if you have a table saw, you just set the blade angle to whatever you need, set the fence to the appropriate width, and run the wood along the fence. This is by far the easiest way I can think of to create a sloped edge on a straight piece of wood.

You can do the same thing with a circular saw by setting the fence, adjusting the bevel on the blade, and running the saw along the fence. This does not give as good a result as the table saw, but it can work.

Using an orbital sander is tough, since there is no way to set a fence, you have to do the work by eye, which is difficult. Recommend you find a table saw to use.

Table saw will be the easiest and once you set the fence and blade angle all should be consistent. A hand plane would be my second choice if you need to shape them individually for some reason. Your multi-tool and sander are not the tools for this.

Of course to do it right you will need one of these limited edition planes. Each is signed and go for $3,222. I still have my Dad's and Grandfather's or I most certainly would buy a couple.

My art gallery clients used to hate it when I leaned ladders against paintings and accidentally put holes in canvas paintings. Don't worry about Mona. When you really look at her she was not all that hot anyhow. A little duck tape on the back and some touch up with 2.5 inch angled sash brush and only you will notice.

If you must get another authentic original. Oscar DaVinci runs a shop out of Brooklyn. You leave him a photo of any piece of art. He sends it off to Taiwan and two weeks later you get your masterpiece by air freight.

If you can take the bottom off to do the work, there are several options. You could bevel the bottom with a table saw, router, or jointer. You could bevel it by hand using a plane.

If you cannot take the bottom piece off, you could sand it using a belt sander for the middle and a pad sander towards the edges. Or you could use a hand plane. Or you could rout the middle part, then finish the ends using a hand plane or pad sander. If you had an orbital tool like a feinmaster, you could use that for the whole thing.

Ok. I can take the bottom off because the cases aren't built yet. I'm having the sashes built by a wood shop and I'm building the cases. I do have an orbital sander and I also have a craftsman multi tool. Similar to a feinmaster I believe. I still don't understand how to slope it in a uniform manner though.

i am assuming exterior. what i do is cut a 15 degree on front and back and to the width desired so it makes a parallelogram.then i put a 3/16 round nose bit in my router and put a drip groove on bottom off sill 3/16 deep and 1/4 to 1/2 in from front edge. i then cut sill and head to sizes desired, cut my legs to length and width needed with bottom being beveled to 15 degrees and drill for pocket screws in back of legs. assemble all together so back of legs, sill,and header are flush and pocket screw together. then after window is installed and rubber flashed accordingly the trim is ready to be nailed and sealed in to place.

wood material used i usually use are cedar, mahogany or pine
